摘　　要：采用无人机遥感技术获取研究区高分辨率遥感影像,通过人工目视解译,建立滑坡、地面塌陷、不稳定斜坡、地裂缝、泥石流等地质灾害的遥感解译标志,探索了一套适合青藏高原地区的地质灾害遥感解译的完整技术流程,为地质灾害应急、监测与治理提供科学依据.研究表明,无人机遥感技术获取的影像分辨率高,可最大程度的提取地质灾害信息,使遥感解译精度更高,适合作为大比例尺地质灾害遥感解译的数据源.通过野外复核,证明基于无人机遥感技术的地质灾害解译效果良好,作为一种高效、快速的调查手段,可在青藏高原地区进行推广应用.Using UAV remote sensing technology obtained high resolution remote sensing images of the study area,through manual visual interpretation,established remote sensing interpretation keys of landslides,ground collapse,unstable slopes,ground fissures,debris flow and explored a complete technical process of remote sensing interpretation of geological hazards which is suitable Qinghai — Tibetan Plateau,to provide scientific basis for geological hazards emergency,monitoring and treatment.The study shows that the high resolution remote sensing image obtained by UAV remote sensing technology can extract geological hazard information by the maximum degree and it is suitable for large —scale geological hazard remote sensing interpretation data sources.Through field review,certified geological hazard interpretation effect,based on UAV remote sensing technology,was good and which can promote using in Qinghai-Tibetan Plateau,as an efficient and fast means of investigation.
